Hey Guys still having trouble really trying to figure out how to set the menu to active and not active for certain cases.

First.

I have a page thats called 'Current' which is also in the header. On that page there are sections that take you to another page. So sorta like blog overview page that take you to single blog posts. But the menu 'Current' doesn't stay active or how do I get it to stay active when i'm in a single blog post?
